The BBULL DUAL SORTER was especially conceived for sorting and distribution
of plastic crates and
cartons with a power of max. 8.000 packs per hour.
A major advantage of the dual sorter technology is due to a constant transfer
width for containers
with different weights.
At the beginning of every transfer process, the weight is defining the required
tranfer energy. By
adaptation of the transfer energy to the container weight, linked with a movement
in conveying
direction while transferring, the BBULL Dual Sorter produces a constant
and accurate
transfer width for filled and empty packs.
The BBULL Dual Sorter works lateral to the conveyor section. The transfer
can be carried out on available slat- or driven roller conveyors.
Because of its compact design, the required space of theBBULL Dual Sorter is very small and a retro fitting in available lines
is
accomplishable without any efforts.

MODE
OF OPERATION

The
system consists of two counter rotating, on one transport bar mounted transfer
segments. The power transmission of the segments occurs from a servo drive.
Both of the two transfer segments consist of a pneumatic cylinder with a roadbed
and a transfer plate which is in contact with the packs during the sorting operation.
For every sorting operation one of the transfer plates will be deployed pneumatically
and conducts the container during the operation with angular synchronism with
the production speed.
At the same time the second segment (passive) will be set back in basic position,
to reject the next container. This happens for every rejection operation.
During the starting phase of the transfer movement, the weight of the pack is
determined. Afterwards a dead weight depending, progressive acceleration of
the crate is calculated by considering as performance data. This progress brings
out the same transfer width between not filled and filled packs.

Starting
phase
After the start signal, the left upper segment is
driven in conveyer speed to the right side, at the same time the pneumatic
controlled transfer movement occurs.

Transfer
phase
After the container and weight calculation is finished, the calculated acceleration
occurs. At the same time the passive segment, which is below, moves to the
left side.

Ending
phase
Shortly after the rejection process is finished, the
next rejection can follow with the following segment below.
